WASHINGTON (AP) – Muslim Advocates, a national legal advocacy and educational organization based in Oakland, California, is denouncing Donald Trump’s victory, saying his views violate the foundation of America’s democracy.

In a statement issued after Trump appeared at a New York hotel to celebrate his victory, the group said it has repeatedly expressed concern about what it said were “undemocratic and unconstitutional policies” proposed by candidates, such as banning Muslims from the U.S. and vilifying Mexican Americans.

The group vowed to use every legal tool available to protect the country against unconstitutional and undemocratic action.

The Republican president-elect has accused Mexico of sending rapists and other criminals across the border. And he called at one point for a “total and complete shutdown of Muslims entering the United States.”

The group says in a statement: “If President-elect Trump wants to bring America together and be a leader for all Americans, he will need to disavow these dangerous proposals and ideas.”
